3( 4z - 1) + 2 ( z + 8) = 2 ( z + 1 )
-----
12z-3 + 2z+16 = 2z + 2
12z = -11
----
z = -11/12

To solve 3%284z-1%29%2B2%28z%2B8%29=2%28z%2B1%29 we first do the multlipying
3%2A4%2Az-3%2A1%2B2%2Az%2B2%2A8=2%2Az%2B2%2A1
12%2Az-3%2B2%2Az%2B16=2%2Az%2B2
Put z expressions to the left hand side and put numbers on the right hand side.
12%2Az%2B2%2Az-2%2Az=2%2B3-16
12%2Az=-11
z=-11%2F12
